Parts for your 2020 Subaru Legacy-Shock absorbers

2020 Subaru Legacy shock absorbers

Shock absorbers are absolutely fitted to the 2020 Subaru Legacy. Subaru’s technical sources — including the 2020 Legacy Service Manual (Chassis/Suspension), Subaru of America’s 2020 Legacy press kit, and the owner’s maintenance guidance — specify a MacPherson strut front end and a double-wishbone rear, both using gas-pressurised dampers. So, shock absorbers are very much relevant to this model.

On this Legacy, the shocks (front strut-type dampers and rear shock absorbers) control spring movement, keep the tyres planted, and tame body bounce after bumps. That helps the car steer predictably, keeps ABS and stability control working at their best, and improves ride comfort on coarse-chip rural roads and pockmarked city streets. Good shocks also reduce brake dive and body roll, so the Legacy feels settled and secure when it’s loaded up for a weekend away or hustling through a wet roundabout.

Servicing wise, it pays to have the shocks checked at every routine service (typically each 10,000–15,000 km or 12 months). A trained tech will look for oil seepage, damaged dust boots, worn top mounts, and uneven tyre wear, then road test for control and rebound. In local conditions — heat, corrugations, and the odd gravel shortcut — many shocks last 80,000–150,000 km, but they can tire earlier if the car tows, carries heavy loads, or lives on rough roads.

• Tell-tales it’s time: persistent bouncing, longer stopping distances, nose-diving under brakes, knocking over bumps, steering shimmy, cupped or patchy tyre wear, or visible oil on the damper body.

When replacement’s due, doing both sides on the same axle keeps handling balanced. Front strut work should be followed by a wheel alignment to set camber and toe correctly. It’s smart to replace strut tops, bump stops and dust boots at the same time, they’re inexpensive and save labour down the track. Quality OE-equivalent or reputable aftermarket units will restore the Legacy’s planted feel. After fitment, torqueing suspension bushes at normal ride height and a brief road test will prevent premature wear and make sure the car tracks straight. Owners who frequently tackle unsealed roads might also consider shocks tuned for rough-surface control for a bit more composure without spoiling everyday comfort.

Popular questions

How long do the 2020 Legacy’s shock absorbers usually last?
In Australia and New Zealand, many see 80,000–150,000 km before performance tails off, but life varies with loads, road quality, and driving style. Regular inspections will spot leaks or fading before they affect braking and tyre wear.

Do you need a wheel alignment after replacing shocks or struts?
Yes — especially after front strut replacement. Alignment resets camber and toe so the Legacy steers straight, avoids premature tyre wear, and the safety systems work as intended.

Should shocks be replaced in pairs?
They should. Replacing both fronts or both rears at the same time keeps damping balanced side to side, preserving stable handling and consistent braking.
